Correct.

and the voltage magnitude is fixed w/ time (sin^2 + cos^2
= constant).

Ummm... Not unless your two hot wires are 90 degrees out of phase and
you're using 2 dimensional wire. The voltage magnitude is 2*v*sin(t).
3 phase is more interesting (something like v*sin(t)-v*sin(t+120deg)).

Maybe you're remembering some current X magnetic field vector from a
previous life?

No, just an unfortunate ill-considered (or, more correctly, really not
at all considered) attempt at a mixed metaphor...which while true
geometrically, has nothing to do w/ the voltage...

Thanks for bringing it to everybody's attention... (Not that
shouldn't have corrected the factual blooper)
